This International Standard specifies fire type-testing
requirements and a fire type-test method for confirming the
pressure-containing capability of a valve under pressure during and
after the fire test. It does not cover the testing requirements for
valve actuators other than manually operated gear boxes or similar
mechanisms when these form part of the normal valve assembly. Other
types of valve actuators (e.g. electrical, pneumatic, or hydraulic)
may need special protection to operate in the environment
considered in this valve test, and the fire testing of such
actuators is outside the scope of this International Standard.

NOTE For the purposes of this International Standard, the terms
"fire type-test" and "fire test" are synonymous.
